which eheim pump??
 

My system will consist of the following: duel rad, res, cpu block, north bridge block, and maybe a gpu block. My question is will the 1250 be enough or should i go for the 1060? Obviously part of the system will be outside the case so my tube lengths will be on the long side. Which brings up another question, if the barbs on the blocks are 1/2 inch should i use 3/8 ID silicon tube or will 1/2 ID sillicon fit tightly enough with clamps? Im still in the early planing stage and haven't bought anything yet so any advice is helpfull as this is my first water cooled system.

i think you'd wanna use the "search" function. i posted a thread just not long ago about the 1060.

So go with the 1060 for the high flow through the blocks and run the rads in parallel to halve the flow through them. does that sound good?

with all those blocks, the 1060 and paralell rads is probably a good idea. you may want to look into the hydrothruster or something else that'll provide some pressure.

bah i lost my linky to the hydro...help me out?

the 1250 is just fine, but the 1060 will be better if you ever need to cool a dual athlon system or something with a huge heat output
